NivoLED® - NL 9000
Visual Signal Indicator for Safe Level Monitoring


The new
signal light has been designed specifically for the most demanding industrial conditions. With its robust construction, versatile applications, and international hazardous area certifications, the NivoLED® is unrivaled in its field. For applications requiring the highest safety standards and clear, reliable visualisation, we have created a solution that meets these unique demands.Reliable Safety and Flexible Integration
Our NL 9000 signal light provides safe and reliable operation in hazardous areas thanks to advanced protection features. Whether in control cabinets or process installations, this signal light integrates seamlessly and is compatible with standard level sensors as well as relay and transistor outputs. This makes it the ideal solution for applications where visual safety and versatility are essential.
Optimal Visibility and Durability in Challenging Environments
The 360° visibility of the NL 9 LED signal light ensures clear recognition even in demanding environments such as dust or fog - and from a considerable distance. Equipped with a dual-colour LED display, this signal light reliably indicates the switching status of electrical equipment in green and red. The translucent PVDF plastic housing is not only durable but also provides high resistance to weather conditions and chemicals.
